probably pretty close to level.I think a stock 67 - 69 dart with 14" tires would be 21 1/2" at the highest point on the rear wheel well.
The higher the the front end the more caster you lose
Not to argue, but actually the front end height has very little to do with caster. However, the height of the rear affects caster a good bit. Caster is the forward or rearward tilt of the steering axis when viewed from the side of the car. So you can see, the height of the rear would much more greatly affect caster than the front. This is why when you jack a car way up in the rear, you normally lose some high speed road stability, because it reduces caster.
